It is proposed to explore the dynamics of charged particles with spin under strong active gravitational forces. The celestial domain with an abundance of astronomical events offers a fertile ground to contemplate the nature of gravitation and the role of spin in gravity. Under extreme conditions not accessible to controlled experimentation, the nonlinearity inherent in the Riemannian and non-Riemannian spin-curvature couplings may significantly modify the behaviour of astrophysical plasma and there is a need for clarification in this respect. Such a clarification may help elucidate cosmological phenomena as powerful as gamma-ray bursts whose underlying mechanism still remains enigmatic since their fortuitous discovery. However a strong indication is that the unstable interaction within the postulated black hole-accretion systems may be important in this context. A further implication is that nonlinear spin-curvature interactions may influence the dynamics of other astrophysical scenarios involving substantial amount of accretion matters constituting of charged particles with spin in the vicinity of strong gravitating sources. They may also be responsible for attenuating gravitational waves emitted, e.g. from colliding black holes or horizon fluctuations, thereby converting gravitational energy into those carried away by electromagnetic radiations. The aim of the proposed research is to develop a clear theoretical description of these effects applicable to observation leading to a greatly enhanced understanding of gravitational interactions in nature.
